Got the book today (quick service).
I am quite pleased with the result. Although there is no dust cover, the book is essentially the same size as my Apple Books (11"x8.5") and the quality of the printing is good. My binding options were 11"x8.5" Imagewrap Matte Hardcover Press Printed Photo Book, Premium Photo Paper. I will try different quality paper for future books just to see the difference.
Once you have completed the book in Aperture, print to a pdf, then remove the inside dust cover photos and the blank pages. Save the cover and back as separate files and delete them from the body of the book. You upload the photo pages as a single pdf and then upload the front and back cover pages. remember to add the text on the binder and away you go !
The one thing to watch is the crop lines - photobook.pro will show you these prior to confirming your order and I had to make a few adjustments to the image positions and then reload the pdf but I forgot about the page numbers - these end up very close to the edge in the finished book. The workaround is to either print without page numbers or add your own as text boxes (a little tedious!).
As an amateur, printing books for my own enjoyment, I am happy with the result and will be using them again in the future.
